Deformation Mechanisms in Titanium and Zirconium Alloys - Superalloys Lecture 3
This set of lectures is on "Deformation Mechanisms in Titanium and Zirconium Alloys" for the Superalloys & High Performance Materials course part 3. This part of the course was taught by Dr Christopher Daniel at The University of Manchester in 2021.
Video 1 describes explains how slip contributes to grain reorientation and recalls the equations for calculating the resolved shear stress (RSS), the critically resolved shear stress (CRSS) and the Schmid factor.
Video 2 will recall the main slip systems in both titanium and zirconium alloys and describe how the slip system activities change with temperature.
Video 3 explains how twinning contributes to grain reorientation and presents the main twinning types in titanium and zirconium alloys.
Video 4 describes the driving forces for recrystallization and recovery processes in terms of boundary and stored energy, which can be used to describe the microstructural changes during annealing (or hot-deforming) of titanium and zirconium materials.
This live lecture includes poll questions and discussion for the "Deformation Mechanisms in Ti and Zr Alloys" topic and was recorded on Monday 22nd February 2021.
